The overall goal here should be to spend time once or twice a month buying and re-packaging food in order to make daily feeding as easy as possible.
I always have two days worth of food in my refrigerator thawing - tomorrow's and the next day's - so that I can simply warm to body temperature and serve.
Watch for sales! Chicken (whole, & leg quarters) is often on sale. Meat departments typically mark down beef & pork nearing expiration date but you must arrive early enough to take advantage of price reductions. Some stores occasionally carry heart (beef, pork, turkey, & chicken). Check with meat department managers.
Some local meat markets prepare a 'blend' for dogs. These blends might contain more veggies than dogs require, so be prepared to ask the butcher about ingredient percentages.
Be skeptical since butchers are typically not knowledgeable about dog nutrition requirements.
Specialty markets - particularly Asian markets - often have fish and meats not found in typical grocery stores.
There are enough raw feeders around that you can likely find a local raw food buying co-op. Search social media, including Google and Yahoo Groups, for 'dog food co-op' or 'Raw Fed dog.' Include your locality name or dog breed to narrow results.
CAUTION: Many people have weird ideas about what constitutes healthy raw feeding ingredients. For your dog's sake, please do your own research first - read Lew Olsen's book.
If there is a meat or grocery distributor nearby, they may sell bulk meat if you make it clear that it is for dogs.
I buy for four dogs (my three and a friend's) so it is more cost-effective to buy bulk from a distributor. Bulk purchases include pork cushion meat (60lbs), chicken feet (40lbs), chicken carcass/frame (40lbs), pork heart (15lbs), beef heart (15lbs), turkey heart (40lbs), turkey necks (30lbs), chicken necks (40lbs), beef liver (12lbs), beef kidney (15lbs). Obviously, I don't buy everything all at once since I have limited freezer space.
I typically cut meat into meal-size portions and freeze until needed. I then thaw, warm to body temperature, and serve with Raw Meaty Bones or calcium supplement, offal, veggies, and a few supplements.

Cut-up and re-packaged meat to make the best use of freezer space.
I have a meat grinder and grind whole chickens and turkey necks for my friend whose Standard Poodle has a swallowing problem. I package ground products in 1lb or 2lb weights in Ziploc® bags. These bags are handy because they stack well in the freezer.
Before you go all-out, first determine what really is meal-sized for your dog(s).
It took 6-8 months of trial feeding to find the ideal amount for each dog in order to maintain their target weight. My starting point was feeding at 2.5% of target body weight (they are now at just under 2% of meat per day). Once every few months I check their weight and feel their ribs for excess fat. There is no rush to do this so relax and take your time.
There was a time when all I had was a refrigerator / freezer. I was feeding three dogs and my freezer was stuffed. That simply made for more frequent buying trips and a really, really packed freezer. My own food was relegated to the freezer door.
I soon bought a 17 cu. ft. upright freezer. It is invaluable and usually full of meal-size portions that I have re-packaged.
Depending on the number and size of dogs you are feeding, it may be worthwhile to invest in a freezer.
